Children's thinking about diversity of belief in the early school years: judgments of relativism, tolerance, and disagreeing persons

Children's thinking about diversity of belief in 4 realms--morality, taste, facts, and ambiguous facts--was examined. Ninety-six participants (ages 5, 7, and 9) were interviewed about beliefs different from their own that were endorsed by characters with different status; their judgments of relativism, tolerance, and disagreeing persons were assessed. Five-year-olds made fewer relative and tolerant judgments than 7- and 9-year-olds. Nevertheless, participants of all ages organized their judgments according to the realm of diversity, thought that some beliefs are relative and some are nonrelative, and made tolerant judgments of some divergent beliefs (and their proponents) but not of others. The findings suggest that, in the early school years, children have multiple and well-differentiated perspectives on belief diversity.     

Longitudinal associations between marital instability and child sleep problems across infancy and toddlerhood in adoptive families

This study examined the longitudinal association between marital instability and child sleep problems at ages 9 and 18 months in 357 families with a genetically unrelated infant adopted at birth. This design eliminates shared genes as an explanation for similarities between parent and child. Structural equation modeling indicated that T1 marital instability predicted T2 child sleep problems, but T1 child sleep problems did not predict T2 marital instability. This result was replicated when models were estimated separately for mothers and fathers. Thus, even after controlling for stability in sleep problems and marital instability and eliminating shared genetic influences on associations using a longitudinal adoption design, marital instability prospectively predicts early childhood sleep patterns.
